Progressives. That's the word I was just trying to think of...

They were the blended ones. No line. No real definition.

Before those ones I was wearing contacts. Short distance one eye and long distance other eye. Took my brain a few weeks to adjust but they were great. Now with my new ones being in separate glasses I'm finding it so much better and you're right, I'm not falling into things or tripping over things, and I live in fear of falling again as it is.
